Filed: 1947-10-28
Abstract: 633,465. Boring-heads. WILLETT, V. W. Oct. 28, 1947, No. 28755. [Class 83 (iii)] In a boring head, the tool holder 26 is carried by a main slide 11, transverse vernier adjustment of which relative to a spigot 1 of the body of the head is obtained by a rack 12 on the slide engaging a spiral thread 3 on a graduated collar 2 which is rotatably mounted on the spigot and capable of being locked to the rack by means embodied in the slide. The tool holder 26 consists of a secondary slide mounted for lenthwise movement of the main slide so as to give an additional transverse adjustment. The slide 11 is secured in the adjusted position by means of a locking element 16 mounted in a cam slot 15 in the slide 11, the element 16 being displaced into clamping engagement with the base-of a diametral groove 14 by means of a screw 20 acting in conjunction with a pin 17. The inner convolution of the spiral thread 3 co-operates with the locking element 16 to provide stops which determine the maximum adjustment of the slide 11. In an alternative form, the means for securing the main slide in adjusted position consists of a loose part of the rack engaging with the spiral thread so that when ejected it can bind to the spiral thread. Specification 554,820 is referred to.

Abstract: 1377068 Heating and cooling apparatus KINS DEVELOPMENTS Ltd E J PERRY and P MOUMOULOFF 19 June 1972 [23 June 1971] 29495/71 Heading F4U A heating and cooling apparatus for use in airconditioning or process plants such as the pasteurization of milk comprises a heating circuit 12 for heating fluid, e.g. water or refrigerant and a separate circuit 14 for cooling fluid, both linked to the same refrigeration units 15, 16, 17. The apparatus comprises four heating coils 11 in the circuit 12 and four cooling coils 13 in the circuit 14 over which air is blown for air conditioning and the circuits are coupled respectively for heat exchange with the condensers 20 and the evaporators 22 in the refrigeration units 15, 16, 17. Heat exchange devices controlled by temperature sensitive devices and connected to a common heat sink circuit 50 are included in the heating and cooling circuits selectively to remove heat from the heating circuit and add heat to the cooling circuit when insufficient heat is added by the evaporators 22. The flow rate through the circuits is controlled by air temperature-sensitive valves 36 to adjust the effectiveness of the heating and cooling coils. The circuits 12, 14 also include by-pass circuits 40, 28 in parallel with the coils 11, 13, which circuits include plate heat exchangers 44, 45, 46 and 32, 33, 34, the flow therethrough being controlled by valves 47, 35 respectively in dependence on pressure controllers 48, 38 located in the heating and cooling circuits adjacent the coils 11, 13. The heat sink circuit 50 passes from an inlet 51 via two parallel paths 53, 54 passing through an oil cooler 23, and sub-cooler 21 in each refrigeration unit. The path 53 are connected by a common pipe 57 to an outlet 52 and the paths 54 are connected to a common pipe 58 linked to the outlet by three alternative paths. The first path comprises pipes 59, 60, 61 each having a valve 62, 63, 64 responsive to the temperature of the refrigerant in the outlet of the sub-coloer 21 as sensed by a controller 65. The second path comprises pipes 66, 67, 68 passing through heat exchangers 66, 67, 68 passing through heat exchangers 46, 45, 44 in a by-pass circuit 40 of the heating circuit 12, the flow therethrough being controlled by a valve 69 controlled by a temperature sensor 70 in the heating circuit. The third path is through pipes 71, 72, 73 through heat exchangers 32, 33, 34 in the cooling by-pass circuit 28 controlled by a valve 74 operated by a temperature sensitive controller 70. A differential temperature controller 75 is positioned between the flow and return lines of the refrigerants in the cooling circuit 14 to cut out successive refrigeration units 15, 16, 17 as requirements dictate.
Patent GB-486520-A (GB)
Title: Improvements in or relating to the manufacture of aryl substituted mono-olefines
IPC: C07C2/70
Filed: 1936-10-30
Abstract: Alkylated aromatic hydrocarbons are prepared by condensing an aromatic hydrocarbon, e.g. benzene, with mono-olefines containing 3 to 5 carbon atoms in the presence of concentrated sulphuric acid at a temperature not exceeding 25 DEG  C. and preferably from 0-10 DEG C., removing the spent acid, washing the product with a relatively small quantity, e.g. 2-5 per cent by volume, of concentrated acid, and then utilizing the latter for a further condensation.  An excess of aromatic hydrocarbon over the olefine, e.g. at least 2 mols. to 1, is used when the mono-alkyl product is desired.  A molar ratio of 1 to 1 results in a high yield of di-alkyl product.  Propylene, benzene, and fresh 98 per cent sulphuric acid plus that from a previous washing stage are passed continuously at high velocity through a long steel tube, the temperature not exceeding 8 DEG  C. The products pass to a separator, spent acid being removed at the bottom and hydrocarbons at the top.  The latter ascend a wash tower against a stream of 98 per cent acid, and are then washed with water and alkali, and fractionated to obtain unchanged benzene, mono- and di-isopropylbenzene.  The used washing acid is continuously mixed with the fresh acid.  Mixtures of olefines obtained by cracking oils and containing ethylene can be used.  The condensation products may be converted to styrene and the like as described in Specifications 486,573 and 486,574.

Abstract: 1379679 Holder for volatile substances L'OREAL 23 June 1972 [24 June 1971] 29601/72 Heading A5G A holder for solid, volatile deodorising, disinfecting and the like substances comprises two members 1 and 7 each having a pair of concentrically spaced, apertured, cylindrical walls 2 and 4, and 8 and 10 respectively. The volatile material is placed within the inner wall 2 of the first member, which fits within the second member, walls 2 and 4 being sliding fits within walls 8 and 10 respectively. Relative rotation of the two members thus restricts to a greater or lesser extent the access of air both to the volatile material and to the annular compartment between the wall pairs 2 and 8 and 4 and 10, through which air may circulate via both the apertures in the outer walls 4 and 10 when these are wholly or partly in registration and also via the holes 6 in the base of member 1. The volatile material may be inserted as a preformed block or as a liquid through appropriate apertures in the base (see Figs. 2 and 5, not shown) and allowed to set. For Figures see next column
